The chain drive project

[jedi-]

nice!

whats the 'grey/green' type coating? I've noticed the same thing on (i'm assuming hardened) rear spindle on my single-sided swingarm hawkGT.

Yes it is case hardening which causes that effect.

Here's an update of the drive sprocket. I felt my gearing was a tad high so I have made another drive sprocket with one less tooth.
You may wonder why I wouldn't simply make another rear sprocket, the reason is I wanted to perfect the front which means any future work with chain drives is even less invasive as to what I machined from my own cases.
A couple of small mods to the design also.It can be swapped out in about 30 mins which is actually less of a hassle than pulling the rear out anyway.
This ratio should be spot on.

great work.

2 questions.... 1. how has it held up? 2. Is your slip-on output shaft all 1 piece (milled with sprocket) or welded on sprocket?

Apparently it didn't work out, as no updates on operation. Plus a 13t sprocket is real hard on chain.
